BRUSH-f-MCHINE.

SPECIFICATION forming part of Letters Patent No. 696,761, dated April.1, 1902.

Application filed Tune 22, 1900.

To @ZZ whom, it may concern:

Beit known that I, HERMAN M. SCHWARTZ,

a citizen of the United States, residing at Northampton, in the countyof Hampshire, State of Massachusetts, have invented a certain new anduseful Improvement in Brush- Machines, of which the following is aspecification, reference being had therein to the accompanying drawings.

In the manufacture of brushes of certain kinds-such, for example, ashair-brushesa bristle block or bristle -die is employed. This block ordie is usually made of metal and is provided with a series of holes orapertures corresponding in size and relative location with the tufts ofbristles in the brush which it is desired to make.

The object of my present invention is toV provide a simple, durable, andefficient brushzo machine for lling the bristle blocks or dies employedin brush manufacturewith bristles.

My invention is fully set forth in the following description, referencebeing had to the accompanying drawings, and the novel features thereofare pointed out and clearlyldefined in the claims at the close of thisspeciiication.

In the drawings, Figure 1 is a side elevation of a machine embodying myinvention,

3o the bristle-hopper being partly broken away. Fig. 2 is a similar viewfrom the opposite side of the machine. Fig. 3 is a front elevation. Fig.4 is a plan view of the bristle-block-supporting device, showing themeans employed for causing the said support -to be reciprocatedhorizontally. Fig. 5 is a sectional View of the bristle-hopper, twobristle-blocks beneath the same, and the support for the saidbristle-blocks. Fig. 6 is a viewin section on 4o line 6 o', Fig. 1.

The frame of the machine consists of four uprights 1, 2, 3, and et, theuprights 1 and2 being at oneend of the machine and the uprights 3 and 4at the opposite end. The uprights at each end are inclined toward eachother at their upper ends, forming an A- shaped frame at each end of themachine. The uprights are also strengthened and stiened by tie-pieces 5.The precise form and 5o construction ofthe frame is, however, not

material. At the top of each pair of uprights is a cross-piece 6. Themain shaft 7 is supported in suitable journals on the said crosspiece 6.On the said shaft 7 are the usual fast and loose pulleys 8 and 9, whichare employed in driving the said shaft. Toward each end of the shaft 7,and preferably inside the uprights of the frame, I secure a cam- Wheel10, having on the face thereof a cam 100, With which a pin 12 engages,the said pin being secured in and projectinglaterally from the upper endof the connecting-rod 13. The lower end of the said connecting-rod issecured to the end of the bristle-hopper 14E. The connecting-rod 13passes through a lug or projection l5, secured to one of the crosspieces5 of the frame, and below said crosspiece is provided with a collar 16,firmly secured thereon. Between the lug 15 and collar 16 is placed aspiral spring 17, which as the rod 13 moves upwardlyis compressed andtends to moves the rod downwardly. The cam formed in the face of theWheel 10 is of the shape shown, Figs. 1 and 2, and operates when thewheel revolves to cause a vertical vibration or reciprocation of thebristle-hopper 14. As the Wheel rotates the pin 12 will be caused toroll or slip from one of the points 11 lof the cam to another, thusraising and lowering the connecting-rod 13 and bristie-hopper 11i fourtimes during each revolution of the Wheel 10. This results in a veryrapid reciprocation through a short range of movement, which isdesirable. This means `for supporting and reciprocating thebristlehopper is duplicated at the opposite end of the machine, as willbe clear. The bottom of the bristle-hopper is reticulated and is formed,

preferably, of Wire-netting 1S. The bristles are placed in thebristle-hopper and are caused by the reciprocation thereof to passdownwardly through the reticulated bottom andv into the bristleapertures or holes 19 in `the bristle-blocks, one of which is shownat20, as will be hereinafter more fully set forth. f

For the purpose of properly agitating and separating the bristles in thehopper and prei venting them from becoming matted and massed together Iprovide an agitator which extends legthwise of the said bristle-hopperand supported on u prights of the frame.

3o more etfectually agitated and separated.

65 in the other direction.

and comprises a rod 2l, having a series of outl one diagonal position tothe opposite, While wardly-extending teeth or pins 22 thereon. Thisagitator is journaled in cross-pieces 23 and 24,located at opposite endsof the machine The shaft or rod 21 of the agitator extends throughhorizontal slots 25 and 26, formed at opposite ends of the said hopper,the said slots being greater in width than the diameter of shaft ro 2l,thereby providing for independent vertical play or movement of thehopper to a slight extent. To one end of the said rod or shaft a pulley27 is secured, to which power is communicated from the main shaft 7 bymeans 15 of the pulley 28 on said main shaft and the connecting-belt29.By this means the agitator-shaft iscaused to rotate,forcin g the teeth22 through the mass of bristles in the hopper and operating to separateand agitate them.

zo In addition to its rotary movement, however,

z5 of a position parallel with the sides thereof,

and will then move horizontally, its opposite ends moving in oppositedirections until it assumes the opposite diagonal position. In this waythe entire contents of the hopper are To give the agitator this swingingor vibratory movement simultaneously with its rotary movement,thecross-pieces 23 and 24, in which the shaft 2l of the agitator isjournaled, are

caused to reciprocate horizontally by the following mechanism: At oneend of the main shaft 7, outsidethe uprights 3 and 4, I secure a pulley30. A shaft 3l is journaled in the uprights 1 and 4 at a somewhat higherlevel 4o than the top of the hopper 14. Outside the uprights 4, on theend of the shaft 31, I secure a'pulley 2, which is connected by means ofa belt 33 with the pulley 30 of the main shaft. The shaft 3l is providedat the opposite ends thereof `with cranks 34 39, the pins of which Workin longitudinal slots 341, Fig. 1, in arms 35 and 40, which are pivotedto the uprights 1 and 4, as at 342. The lower ends of the arms 35 40 areprovided with longitudinal 5o slots 36, receiving pins 37, provided onthe horizontal supports 23 and 24.' The opposite ends of the horizontalsupports 23 24 are provided with slots 371, through which pins 38 on theuprights 2 and 3 project. By this arrangement the throw of the cranks 3439 causes the horizontal supports 23 24 to have a horizontalreciprocating movement.

The agitator-shaft 21 is journaled at one end in the horizontal support23 and at the 6o opposite end in the horizontal support 24, and

the cranks 34 and 39 are set on opposite phases, so that as thehorizontal support 23 moves in one direction the horizontal support 24at the other side of the machine moves This causes the agitator-shaft 2lto. assume vdiagonal positions within the bristle-hopper 14 and to movefrom at the same time it is given a rotary movement, and thus the teethor pins 22 on the agitator are caused to engage the entire mass ofbristles within the hopper and to so act upon the said mass of bristlesas to separate the mass and prevent it from matting or massing together.

Directly underneath the hopper 14 and suitably supported on the frame Iplace a frame comprising end pieces 4l 4l and bars 42,which extendbetween said end pieces and are secured thereto. The said bars form asupport for the bristle blocks or dies and at the same timepermitanyloose or surplus bristles which do not enter the holes in the dies orwhich are brushed off the dies by the operator to fall between the bars42 into the receptacle 43 below the latter. In the operation of fillingthe bristle-blocks they are placed directly beneath the hopper 14, and Ihave found it desirable to slowly move the said bristle-blockslaterallyin the operation of iilling them. One of the advantages of thusmoving the bristleblocks while they are being filled results from thefact that since the bottom of the hopper is formed from wires some ofthe wires may be located directly over some of the bristle holes orreceptacles in the bristle-blocks, and will thus to some extentinterfere with the proper and speedy iilling of the hole or receptaclewith the bristles. By moving the die-blocks laterally or diagonally thesaid holes will be uncovered and all of the bristle receptacles or holesin the bristle-blocks Will be quickly and evenly filled. To this end Iplace the bristle-blocks on 'a horizontally-reciprocating portion of thebarred support, said reciprocating portion being directly underneath thehopper. This portion of the support consists ot' a frame comprising endpieces 44 44 and a series of connecting-bars 45, secured at either endto said end pieces 44. 'Each of the end pieces 44 is provided with aprojecting guide or support 46, which passes through an opening in theproximate end pieces 41 and serves to support thereciprocating frame,upon which the bristleblocks are placed while being filled. The saidreciprocating frame has preferably a slow reciprocating movement betweenthe end pieces 4l, the extent of its reciprocation being comparativelyslight. For the purpose of causing reciprocation ofv the said frame Iprovide one of the projections 4b' with a link 47, which is pivoted at49 to the face of a ratchet-wheel 48. The said wheel48-is mounted upon asuitable arbor carried bya bracket 48a, Fig. 2, and is actuated by meansof 'a bent lever 50, having a tooth 5l, whichengages with the teeth ofthe ratchet 4S. The lever 50 is pivoted to a cross-piece 52, extendingbetween the uprights 3 and 4, and its upper end projects over and is inproximity to the face of the pulley 32. On the face of the said pulley32 I secure a projection or tappet 53, which as the pulley 32 revolvesacts against IOO IIO

one side of the lever 50, moving the said end away from the faceof theupper end of the pulley, causing the lower end of the said lever to movein the opposite direction and to rotate the ratchet 4S the space of onetooth.

The upper end of the lever 50 is held by" means of a suitable springagainst the face of the pulley 32, so that after the projection 53 haspassed the end of the said lever 50 the said end will be snapped backagainst the face of the pulley, throwing the lower end of the said lever50 outwardly over the next tooth in the ratchet 4S in position to againmove the ratchet the space of one tooth at the next revolution of thepulley 32. By this means a slow reciprocation of the barred frame, uponwhich the bristle-blocks are supported while being lled, is effected.`

The receptacle 43 is provided, as above described, for the purpose ofcatching the surplus bristles which failto get properly into the bristleholes or receptacles in the bristleblocks. The said receptacle 43 has aninclined bottom 55 extending from the front of the machine rearwardlyand downwardly to a point at the rear of the bristle-hopper. The rearwall of this receptacle is shown at 56. As the bristles fall into thereceptacle 43 they slide downwardly and rearwardly toward the lowestposition thereof and are then carried upward by a toothed conveyer 57,which re-` turns them to the bristle-hopper 14. This conveyer isactuated by the shaft 3l, previously described, and consists of asheetof smooth flexible material secured at its opposite edges to a beltformed of material suitableto engage the guide-rolls overwhich itpasses. The conveyer passes over the shaft 3l, thence downwardly andrearwardly over the guide-rolls 58, located at and engaging with theedges of the conveyer,t'he'nce outwardly and forwardly around the shaftor roll 59, near the deepest part of the receptacle 43, thence uparoundthe guide-roll 60. The conveyer is provided with transverse rows ofcurved fingers 62. The fingers 62 pass downwardly into the mass ofbristles in the deepest portion of the receptacle 43 and then passupwardly, carrying a portion of the bristles with them, and as they passover the shaft 3l, above the rear edge of the hopperl4, the bristlescarried upwardly from the receptacle 43 would be discharged into thehopper.

The machine lls the bristleblocks evenly and quickly and is automaticinits operation. The operator requires only to place the emptybristle-blocks in position underneath the hopper, withdrawthem afterthey have been filled, and brush off the extra or surplus bristles.
